Answer:
a
The machining time is
b
The maximum metal removal rate is
Explanation:
From the question we are told that
The length of the work piece is
The width of the work piece is
The cut Depth is
The chip load is
The number of teeth is
The cutting speed is
Now in order to obtain the actual machining time to make the pass across the surface
We first obtain the speed of rotation of the machine
The cutting velocity is mathematically represented as
Where d is the diameter given as 150mm
N is the speed of rotation
Making N the subject of the formula
Next we need to obtain the feed rate this is mathematically represented as
Substituting the values accordingly
The displacement of the milling operation is mathematically represented as
The machining time is mathematically represented as
The maximum metal removal rate is mathematically represented as
Substituting values accordingly
